  • Copolymers of halogenated olefins and halogenated co-monomers
    Patent number: 11725071
    Abstract: Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.
    Type: Grant

  • Fluoropolymer gas separation films
    Patent number: 9457315
    Abstract: The invention relates to a novel film, membrane or powder media made from fluoropolymers, especially PVDF-based and ETFE-based polymers, which are suitable for separating gases, especially carbon dioxide, from a gas mixture. The novel film has good selectivity, high permeance, good mechanical properties, and exhibits a high resistance to oxidant and acid attack. The separation film is especially useful in harsh and corrosive environments.

  • High melting fluoropolymers
    Patent number: 9447214
    Abstract: The invention relates to a method for making copolymers of 2,3,3,3-tetrafluoropropene and vinylidene fluoride by an emulsion polymerization process having unexpectedly high melting temperatures, even at low crystallinity levels. The invention involves adjusting the microstructure of the copolymers through a controlled polymerization to obtain controlled microstructure copolymers with unique properties, including those with high melting temperature and low crystallinity.

  • Synthesis of making 2,3,3,3-tetrafluoropropene containing fluoropolymers
    Patent number: 8809471
    Abstract: The invention relates to a method for synthesizing 2,3,3,3-tetrafluoropropene containing fluoropolymers using non-fluorinated surfactants in an emulsion process. No fluorinated surfactants are used in the process, and a persulfate initiator is used as the primary initiator. The process produces high molecular weight copolymers.
